Conjuro
La criatura objetivo obtiene +3/+3 hasta el final del turno y debe ser bloqueada este turno si se puede.
If each creature the defending player controls can't block for any reason (such as being tapped), then the affected creature isn't blocked. If there's a cost associated with blocking the affected creature, the defending player isn't forced to pay that cost, so it doesn't have to be blocked in that case either.
